View Full Version : [SOLVED] Xubuntu resets permission to Firewire on Restart

It seems Xubuntu keeps on resetting the permission settings for the 1394 driver after I restart. Each time I have to sudo thunar and change it to Read & Write, but it changes it back to none after the restart. I was wondering why that is and what would be the best way to stop this from happening?
Thanks in advance!

Hi and welcome to the forums!
What are the default permissions of the device?
ls -al /dev/name
where name is the name of the device.
If the video group has read/write permissions then simply add your user to the video group:
sudo gpasswd -a user video
where user is your login name.
Log out and log back in.
Otherwise you have to create an udev rule. Check out the community doc:
community/Firewire
the ArchLinux wiki:
http://wiki.archlinux.org/index.php/Udev
and
http://www.reactivated.net/writing_udev_rules.html
If you are unsure how to write the rule, open a terminal and post the output of:
sudo udevadm info -a -p $(sudo udevadm info -q path -n /dev/name)
Replace name with the name of the device.
You have to create a new file for the rule, run:
gksu mousepad /etc/udev/rules.d/99-custom-1394.rules
to create the file and open it in the text editor.
To set the permissions you need something like:
KERNEL=="raw1394", GROUP="video", MODE="0664"
NOTE: This sets read/write permissions for root and the video group and read permissions for others, so you may have to add your user to the video group.
